74LVT162244BDL,112

Overview

The Nexperia 74LVT162244BDL,112 is a 3.3 V 16-bit buffer/driver with 3-state outputs housed in a 48-lead SSOP package (SOT370-1). It features four output enables and includes series resistance of 30 Ω per output to eliminate external termination resistors. The device operates within a supply voltage range of 2.7 V to 3.6 V and supports an input voltage up to 5.5 V. It provides an output capability of +12 mA/-12 mA and functions across an ambient temperature range of -40 °C to +85 °C.

Feature Summary

• Integrated 30 Ω series output resistance removes the need for external termination components.
• Bus-hold data inputs maintain logic states without requiring external pull-up resistors.
• IOFF circuitry enables partial power-down mode by disabling outputs during power loss.
• Overvoltage tolerant inputs allow direct interfacing with 5.5 V signals while powered at 3.3 V.

Applications

• High-speed 16-bit bus interface systems
• Mixed-voltage signal translation between 3.3 V and 5 V domains
• Live insertion or extraction peripheral connections

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current product status documentation. Confirm that the SSOP package variant matches the design requirements, as datasheet revisions may indicate changes to available package types or manufacturing sites. Ensure compliance with RoHS and REACH regulations relevant to the target market.

Selection Notes

Select this component when designing 3.3 V logic interfaces requiring integrated termination to reduce board space. The wide input voltage tolerance facilitates connection to legacy 5 V buses. Verify that the thermal performance of the SSOP package meets the application's heat dissipation needs under maximum load conditions.

Part Context

This part belongs to the 74LVT family of low-voltage TTL-compatible logic devices. It serves as a line driver and buffer for high-speed digital applications. The 74LVT162244B series specifically addresses the need for controlled impedance on long traces through built-in termination resistors.

Replacement Considerations

The 74LVT162244ADGG is a TSSOP variant of the same logical function. Verify pinout compatibility and package dimensions before substitution. Note that the 74LVT162244BDL (SSOP) was removed from the datasheet in revision 5; confirm current production status with the manufacturer.
